Which form of Proglumide do you sell? And is there a ‘salt’ of it?

I’m asking because I managed a few years back to purchase some proglumide from a chem company [removed for business reasons].
However it didn’t seem all that effective to me, and on the other hand I’m fairly positive that what I got was actually Proglumide.
Though what I’m starting to think now is they gave me it in it’s pure form, and I’m not sure if the pure form has a good bioavailability when taken orally.
I’ve already made an order for a bottle of your stuff and am curious to see if it works any different/better for me than the powder I procured on my own.
So my question is (and I emailed you about this too) what form of Proglumide are you selling? Is it a more easily absorbed ‘salt’? Is there even a ‘salt’ of Proglumide?
I just wanted to ask publicly because I think this might be important information.
Thanks
